Definitions

  • Such a clutch is off JP-06058478A known.
  • the invention relates to the use of a refueling coupling for the filling of storage devices that are suitable for cryopreservation.
  • cryoprint storage is characterized in that cryogenic hydrogen, which preferably has a temperature between 30 and 80 K, at a pressure of several hundred bar, preferably at a pressure of 250 to 350 bar, is stored in a suitable container. While for the aforementioned types of storage high pressure storage, liquid storage and storage Metal hydrides already refueling methods as well as corresponding refueling couplings exist, this is not the case with the cryopressure storage.
  • test facilities containers are connected by solid pipes and / or hoses with a filling device. A filling of these containers is possible only after extensive inerting and pressure cycle rinses and leak tests.
  • Object of the present invention is to provide a generic refueling coupling, which allows refueling of containers that are suitable for cryopreservation.
  • the aim of the invention is therefore to provide a simple and cost-effective method for the filling of Kryoyak counterpartern means of a special Kryoyakkupplung, which is intended to enable a comparatively straightforward operation with respect to handling and filling process, such as the known refueling coupling for GH 2 and LH. 2
  • the media lines fed via the medium of the refueling coupling and is discharged from this, not shown.
  • the refueling coupling has a coupling plug S and a coupling socket D.
  • a movable in the axial direction pipe R is arranged in the coupling connector S in the coupling connector S .
  • This can be designed as a piston drive pneumatically or hydraulically, but also an electric drive, for example. By a spindle, is possible.
  • the conduit R extends beyond the parting plane T out into the coupling socket D or a cylinder space 5 provided in this, so that a provided in the front region of the conduit R media opening 9 with the inlet opening in the coupling socket D arranged media line L comes to cover. In this position, the medium to be filled can flow through the refueling coupling.
  • the conduit R is now formed insulated, for which purpose the actual media conduit, for example, is surrounded by a vacuum insulation 1.
  • the medium flowing through the conduit R can be thermally insulated against the warm parts of the coupling plug S in the radial direction.
  • the term "warm” below temperatures between -40 to +85 ° C meant, while the term “low temperatures” for temperatures below -40 ° C and the term “cryogenic temperatures” for temperatures between -270 and -150 ° C stand.
  • a first insulating body 2 is arranged, while the coupling socket D has a corresponding to the first insulating body 2, movable in the axial direction of the second insulating 6.
  • This is arranged in the mentioned cylinder chamber 5 and preferably designed to be spring-loaded. It thus fulfills the function of a spring-loaded check valve.
  • conduit R, first insulator 2 and second insulator 6 are sealed gas-tight. This is achieved with the seals 3, 4 and 7.
  • the cryogenic sections or parts of the coupling system are designed according to the invention such that they can lead the (cryogenic) medium isolated from the outer, warm sections, without a direct sealing of the medium takes place at cold temperatures.
  • connection or clamping of coupling plug S and coupling socket D - represented in the figures by a screw V - can in principle be realized with any mechanism that withstands the maximum occurring or required pressure.
  • a quick clamping with ball-in-groove-clamping or molding-in-groove-clamping is possible.
  • Coupling plug S and coupling socket D are advantageously flanged together by means of a quick coupling system, as it is already used in LH 2 - and GH 2 refueling couplings.
  • the coupling plug S In its region facing the coupling socket D, the coupling plug S has at least one sealing element 10 which seals off from the surroundings and which is gastight Sealing of the flange allows.
  • a sealing sealing element may additionally or alternatively also be arranged in the coupling socket D.
  • the conduit R is moved beyond the parting plane T out into the coupling socket D - as in the FIG. 3 is shown, comes in its final position provided in the front region of the conduit R media opening 9 with the inlet of a arranged in the coupling box D media line L to cover, so that an overflow of medium from the coupling plug S can be done in the coupling box D.
  • the refueling coupling according to the invention preferably has means for detecting the position of the conduit pipe R. By means of at least one corresponding sensor, the proper position of the conduit R is detected and only then the filling with the (cryogenic) medium started.
  • the conduit R and thus also the first insulating body 2 are moved back into the coupling connector S.
  • the sealing of the coupling plug S to the environment is ensured by the warm seal 10 during the entire filling process.
  • the sealing of the Coupling socket side D takes place with the coupling socket side second insulating body or check valve 6 also with a warm seal 7. This is arranged such that it is not flooded and cooled during the filling process.
  • the refueling coupling according to the invention allows due to their construction that immediately after completion of the filling process without time-consuming Anürmvorgang coupling plug S and coupling socket D can be separated and a permanent seal the open flange sides can be achieved to the environment. Lengthy rinsing and warming before, during and / or after the connection of the coupling plug and coupling socket are therefore unnecessary.
  • the coupling plug S and / or the coupling socket D are preferably associated with means for heating and / or cooling.
  • coupling plug S and / or coupling socket D can be provided with (a) heating device (s) 11/11 ', which prevent cooling of the warm components by supplying heat. Due to the mechanical connection with the coupling socket D and the use of highly conductive materials of the flange connection and the corresponding components of the coupling socket D are kept at ambient temperature.
  • heat can be supplied by means of a heating element or by a structural design of a thermally conductive connection to this area.
  • the tightness of the flange connection by means of a second, provided on the coupling plug S seal 12, which forms a test room, are monitored.
  • a suitable test gas is supplied to the test room via line 13.
  • the refueling coupling according to the invention achieves the stated object, namely to cope with high pressures and cryogenic temperatures within a coupling system.
  • the required additional design effort in comparison to known LH 2 and GH 2 refueling couplings seems acceptable in view of the achievable advantages. Therefore, the refueling coupling according to the invention is particularly suitable as a refueling coupling for the filling of storage devices that are suitable for cryopreservation.
  • the refueling coupling according to the invention can also be used for the filling of LH 2 and GH 2 storage devices.
